Has anyone had any success using DVDinfoPro (or any other scanning tool) with an internal drive in an external enclosure? I haven't had much success, and the manufactures say that they don't work...

so I guess that comes to the question: is there any good external dual layer burner out there?!?! I looked at the last 6 or 7 reviews on the external section and none of them scored more than 3 or writing. I guess as long as you can get a good scan you can weed out the bad burns...
